Relativistic description of two-photon bremsstrahlung process within the framework of delta-approximation
Approximate approach for description of two-photon bremsstrahlung emitted by the relativistic projectile scattered in a spherically-symmetric filed of the target is suggested. It based on the accurate treatment of the analytical structure of singularities in relativistic one-photon free-free matrix elements. For the case of Coulomb field of the target the closed-form analytical expressions for ...
متن کاملRelativistic effects in polarizational bremsstrahlung
We review the achievements of the theory of polarization bremsstrahlung of relativistic particles, including the case when both colliders have internal structure. The main features which the relativistic effects bring into the problem are discussed and illustrated by the results of numerical calculations.
متن کاملPolarizational bremsstrahlung in non-relativistic collisions
We review the developments made during the last decade in the theory of polarization bremsstrahlung in the non-relativistic domain. A literature survey covering the latest history of the phenomenon is given. The main features which distinguish the polarization bremsstrahlung from other mechanisms of radiation are discussed and illustrated by the results of numerical calculations.
متن کاملPolarization transfer in relativistic electron-nucleus bremsstrahlung
The emission of circularly polarized photons during the scattering of fast spin-polarized electrons from heavy nuclei is studied within the Dirac–Sommerfeld-Maue approach. Predictions are made for the dependence of the polarization correlations C32 and C12 on collision energy, photon energy and nuclear charge. A comparison with pilot measurements of the transmission asymmetry, sensitive to C32,...
متن کاملInverse bremsstrahlung in relativistic quantum plasmas.
We study the absorption of an intense electromagnetic wave in a plasma by inverse bremsstrahlung, in the relativistic quantum regime, by using the Klein-Gordon (KG) equation. We examine the following points: (1) the solutions of the KG equation in the absence of collisions; (2) the transition probabilities between electron momentum states, and (3) the effective collision frequency in the weak a...
